  2. 2. Contents: 2 • Introduction • Types of pharmaceutical packaging • Packaging materials • Quality control test for plastic • Quality control test for closures • Quality control of collapsible tubes • Quality control of metallic tins • QC test for secondary packaging materials
  3. 3. Packaging is the process by which the pharmaceuticals are suitably placed so that they should retain their therapeutic effectiveness from the time of their packaging till they are consumed. Definition: • “Packing is the art and science which involves preparing the articles for transport, storage, display and use.” • Pharmaceutical packaging is the means of providing protection, presentation, identification, information and convenience to encourage compliance with a course of therapy. Composition of package: (a) Container (b) Closure (c) Carton or Outer (d) Box INTRODUCTION 3
  4. 4. Primary Packaging: This is the first packaging envelope which is in touch with the dosage form or equipment (i.e. bottle, cap, cap liner, label etc). The packaging needs to be such that there is no interaction with the drug and will provide proper containment of pharmaceuticals. E.g. Blister packages, Strip packages, etc. Secondary Packaging: This is consecutive covering or package which stores pharmaceuticals packages in it for their grouping. E.g. Cartons, boxes, etc. Tertiary packaging: This is to provide bulk handling and shipping of pharmaceuticals from one place to another. E.g. Containers, barrels, etc. Types Of Pharmaceutical Packaging: 4
  5. 5. The following materials are used for the construction of containers and closures 1. Glass: - (i) Type-I-Borosilicate glass (ii)Type-II-Treated sodalime glass (iii)Type-III-Regular soda-lime glass (iv)Type-NP-General purpose soda lime glass (v)Coloured glass 2. Metals: (i) Tin (ii) Iron (iii) Aluminium (iv) Lead. 3. Plastics: (a) Thermosetting resins: (i) Phenolics (ii) Urea (b) Thermoplastic resins: (i)Polyethylene (ii)Polypropylene (iii)Polyvinylchloride (PVC) (iv) Polystyrene (v)Polycarbonate (vi)Polyamide (Nylon) (vii)Polyethylene terephthalate (PET) 4. Rubber: (i) Natural rubber (ii)Neoprene rubber (iii)Butyl rubber. Packaging Materials 5
  6. 6. According to British standards institutes plastics represents; “ A wide range of solid composite materials which are largely organic, usually based upon synthetic resins or upon modified polymers of natural origin and possessing appreciable mechanical strength. At a suitable stage in their manufacturing, most plastics can be cast, molded or polymerized directly into shape”. Plastics 6
  7. 7. USES Used for many types of pack including; rigid bottles for tablets and capsules, squeezable bottles for eye drops and nasal sprays, jars, flexible tubes and strip and blister packs. ADVANTAGES • Least expensive than glasses • Ease of transportation • No risk of breakage • Flexible • Light in weight DISADVANTAGES • They are not as chemically inert as Type -I glass. • They are not as impermeable to gas and vapour as glass. • They may possess an electrostatic charge which will attract particles. 7
  8. 8.  Leakage test  Collapsibility test  Water permeability test for plastic containers (injectable preparations ip 1996):  Clarity of aqueous extract  Transparency test  Biological tests Quality control test for plastic 8
  9. 9. 1) LEAKAGE TEST:  Fill 10 containers with water, fit with intended closures and keep them inverted at room temperature for 24hr.The test is said to be passed if there is no signs of leakage from any container. Leakage test for plastic containers (non-injectables & injectables 1996 IP): Fill 10 plastic containers with water and fit the closure Keep them inverted at room temperature for 24 hrs No sign of leakage should be there from any container
  10. 10. 2) COLLAPSIBILITY TEST:  This test is applicable to the containers which are to be squeezed for removing the contents. A container by collapsing inward during use, yield at least 90% of its normal contents at the required rate of flow at ambient temperature. 3) WATER PERMEABILITY TEST FOR PLASTIC CONTAINERS (INJECTABLE PREPARATIONS IP 1996): 10
  11. 11. 4) CLARITY OF AQUEOUS EXTRACT:  Select unlabelled, unmarked and non laminated portions from suitable containers, taken at random. Cut these portions into strips, none of which has a total surface area of 20sq.cm.Wash the strips free from extraneous matter by shaking them with at least two separate portions of distilled water for about 30sec. In each case and drain off the water thoroughly.  Thus processed sample is taken in to the flask, previously cleaned with chromic acid mixtures and rinsed with several portions of distilled water and added 250ml dist water. Cover the flask and autoclave at 121⁰C for 30min. Carry out the blank determination using 250ml dist water. Cool and examine the extract, it should be colourless and free
  12. 12. 5) TRANSPARENCY TEST: Standard suspension preparation: 1gm hydrazine sulphate in 100ml water and set aside for 6hr. Take 25ml of this solution and add 25ml of 10%w/v hexamine and stand for 24hr. Test solution preparation: Sample is prepared by 16fold dilution of the standard suspension. Fill 5 containers cloudiness detectable when compared to water filled84 containers. Absorbance is measured at 640nm and the range is within 0.37 and 0.43.
  13. 13. 6)BIOLOGICAL TESTS: A)Systemic Injection Test: ⚫ Test animal – Albino Mice ⚫ Inject each of 5 mice in test group with sample or blank observe the animals immediately, again after 4hr & then at 24, 48, 72hrs. ⚫ If none of animals shows significant greater biological reactivity than the blank the sample meets the requirements. ⚫ Limit- If abnormal behavior such as Convulsion or Prostration occurs or if body weight loss is greater than 2g, the sample does not meet the requirements. B)Intra Cutaneous Test: ⚫ Test animal- Rabbit ⚫ Examine the sites of for any tissue reaction like erythema, oedema, neuosis at 24, 48, 72 hours after injection. ⚫ Limit- difference between the scores of sample and blank should be lesser than 1.0. C)Eye Irritation Test On Rabbits:  Test animal - albino rabbits  Limit- Sample extract shows no significant irritant response during the observation period85 with blank extract.
  14. 14. CLOSURES A closure is the part of the package which prevent the contents from escaping and allow no substance to enter the container. Closures are available in five basic designs: 1. Screw on, threaded or lug 2. Crimp on(crowns) 3. Press on(snap) 4. Roll on and 5. Friction 14 Quality Control Test 12/8/2018
